Cubs Claim RHP Guillermo Moscoso off Waivers from Toronto

To make room for Moscoso on the 40-man roster, right-handed pitcher Arodys Vizcaino has been placed on the 60-day disabled list as he continues to recover from Tommy John ligament replacement surgery.

Moscoso, 29, is 11-12 with a 4.16 ERA (89 ER/192.2 IP) in 57 major league appearances (24 starts) covering four seasons with Texas (2009-10), Oakland (2011) and Colorado (2012). He made 23 big league appearances in each of the last two seasons, with 21 of his 23 outings occurring as a starter with the Athletics in 2011 and 20 of his 23 appearances as a reliever last year with the Rockies.

The 6-foot-1, 200-pound Moscoso went 8-10 with a 3.38 ERA (48 ER/128.0 IP) with the Athletics in 2011 before going 3-2 with a 6.12 ERA (34 ER/50.0 IP) last season with Colorado. He began spring training with the Kansas City Royals before being claimed off waivers by Toronto on March 16.

A native of Venezuela, Moscoso was originally signed by the Tigers as a non-drafted free agent in 2003. He is 44-31 with a 3.90 ERA (278 ER/641.0 IP) in 132 minor league appearances, 107 of which have come as a starter.
